[Android Head-Units] adit9989:
Thanks, this was fast ! Rooting worked ! Used Framaroot. Installed Busybox, all OK now. This solves the "Incompatible apps" problem also (manually edit or use this app: http://codekiem.com/2013/02/13/market-helper/. )

For some of the hidden setting use this: http://xdaforums.com/showthread.php?t=1400615. Just don't use the extra features on it some are Nook specific but the settings part work. If somebody will add access to TTS settings directly it's a plus. For example Ivona TTS (free) does not have a button from app to TTS settings nut SVOX does so it's not a big deal. My Navi program ( IGo) uses the Android TTS does not come with one like Sygic (did not try Sygic, may try it as an alternative but like I said Primo works. Just needs editing of the sys.txt if you want to use the "sdnavi" card.

From the manual it looks like the GPS chip is this one: http://www.telit.com/en/products/satellite.php?p_ac=show&p=114 (JN3). Like I said, not bad fast boot and sensitive.

On the remote I checked the battery, plugged it in a few times but nothing. Not sure if the remote itself is OK, the LED does not light when a key is pushed).

Steering wheel controls - thanks for info. This is a custom car unit so it includes a harness cable.( Search on ebay "Android santa fe 2013") The cable has a plastic box (CAN bus?) which I think should do the job. Same unit exact hardware is available as a CE version, but I wanted Android. I'm sure you will find it in other car specific versions (seen it for Toyota somewhere).

They make first a universal unit, for cars which accept standard 2 DIN and after make "custom" car unit, which have a custom faceplate and a custom harness cable for the car. The unit itself including software is the same. For example on my car would be impossible to use a standard 2 DIN without adding a custom faceplate.Here is a link to the same unit but with Toyota faceplace and harness cable: http://www.aliexpress.com/item/Car-...JETTA-TIGUAN-TOURAN-EOS-SHARAN/666096270.html

Unfortunately the instructions page with the mounting is very poor without to much info. They show 2 wires for "steering wheel control" but on the shop manual for may car radio it shows 1 wire for steering wheel control, which is fishy. Trying to get more info from the seller.There are solutions which use the IR remote input which need to be wired, this is how I came to realize that the remote does not work. Somehow it's hard to believe they did not test the design, this is why I think I may have a defective harness cable so I'm trying to get a secondary harness cable if possible from them. Not sure if will work, those Chinese sellers always appear to be working directly with the manufacturer (or represent them) when in fact they just buy the devices and resell them.

I would like to get the Volume up/down working, its the only function I use often. It's more like I lose a feature I already had with the OEM radio , not something I can not live without :( I'm not familiar with steering wheel controls work so of course I would appreciate some links or more info at least how can be debugged.

Another note, I was able to set the volume working properly on my Navi app. I can set which channel to use for navigation, set it to "Notification channel" which has a separate slider in the unit settings. You may need to play with this and different apps may have different way of dealing with it. The Volume button controls the system volume not the running app volume.

The rearview image bypasses the OS goes directly to LCD from the camera this is why is instant. What I wanted to say is that if you backup to get out you don't even see that the unit is booting, as you get the back image. :) by the time you finished and moved fro reverse it already boot. Ive read about some barand name units which take 30 seconds to boot, so 10 seconds is not bad. The Navi program will take also some second to boot but I don't use it all the time, is not set to boot always only when I need it.

I've got also a camera which mounts in the light place above the license number. Again, found one on eBay which fits perfect the type of car (size, screw places) and is much cheaper than local ones.
